METALLIC BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 524,955, dated August21, 1894.

I Application filed December 14, 1893- Serial No. 493,689- (No model.) i

To all whom it may concern.-

Be it known that 1, JAMES B. RYAN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Metallic Bedsteads,of which the following is a specification, reference being had thereinto the accompanying drawings.

Figure 1, is a vertical transverse section of a bedstead containing myinvention, part of the head end framework being broken away. Fig. 2, isa partial horizontal section taken on line 00 to Fig. 1. Fig. 3, is adetached view, enlarged, of one of the the truss-bars. Fig. 4 is adetail.

This invention relates to the construction I of metal bed-steads and hasfor its object the providing of a bed-stead of that class with a cheapand efficient support for a spring bed of some of the types which are incommon use, such supports being formed of metal.

Referring to the drawings, A are the posts and B B the side rails. Asshown in the drawings, particularly Fig. 1, the side rails are made ofangle-iron so disposed that the web or rib b projects inward from theupper edge of the web or rib b, so that the outer faces of these websare exposed to view instead of the inner faces as is the case with someof the prior beds.

C 0 indicate corner pieces or blocks, by means of which the ends of therails B Bare attached to the posts; but as my invention does not pertainto the construction of these corner pieces not, in fact, to anyparticular means of connecting the rails to the posts, I have onlyindicated these pieces conventionally; because any usual, approved, orconvenient mode may be adopted for attaching the rails to the posts.

D, E, F, are the truss bars for supporting the spring bed or mattress.These truss bars are by preference made of round iron rods and each hasa central upwardly curved or arched section D, with reverscly bentsections E, E, connecting the arch portion with horizontal supportingends F, F, bent at about right angles to the sections E, E, and adaptedto rest upon the upper faces of the webs b b of the side rails. Ipropose to flatten the sup porting ends F, F, and make them of a lengthwhich corresponds substantially to, or less than, the width of the websb b; and, as indicated in the drawings, the length and shape 'of thesections D, E, are such that the upper outer faces of the sections E Efit quite closely between the inner edges of the webs, so as to preventthe truss bars from moving endwise to such an extent as to thrust theends of the supporting sections or arms F F beyond, or even too near,the outer edges or faces of the rails B, B.

A downward movement of the crown of the arch, D, will thrust outward thelower ends of the sections E, E, springingthem slightly and liftingupward"'upon the outer ends of the sections F, F, which upward movementwill be resisted by the weight of the superimposed bed resting thereon;whereby the elasticity or resiliency of the truss-bars operates in a waywhich is entirely different from that which occurs in a bed wherein anarched bar having horizontal end extensions is secured to the under sideof bed rails; or one having a flat or straight section with upturnedends hung upon the side rails; or one having the ends ofan arch restingon the rails with the entire bar above its support; in which latter caseguides are needed to keep the arch in an upright position, whereas if mytruss-bar is tilted sidewise it tends to right itself.

G is the lower slat, H the upper slat, andI I interposed springs of aspring bed bottom adapted to be used with my invention.

I propose to make the length of the sections E E such that the centralportions of the arched section D will be about level with the upperfaces of the side rails so as to engage with and'forma central supportfor the spring bed bottom or mattress when the latter is in ordinaryworking position, substantially as is indicated in Fig. 1, where it willalso be seen that by reason of the peculiar shape of the bar no portionof it projects below the plane of the rails so as to be seen when thebed is in use, or beyond their outer edges, even when narrow webbedangle-iron is used.

While I have shown in the drawings a wellknown form of spring bed whichis adapted for use in connection with my invention, I do not wish to belimited thereby; because there are many other well-known beds andmattresses which may be substituted therefor. Of

course the number of these truss bars which should be used in any givenbed should be Varied according to the requirements of each particularcase. Owing to the arched form of these bars, they may be made quitesmall in cross section and have sufficient elasticity to supplement oradd to the springiness of the bed; and While, for ordinary uses Ipropose ro make them of round iron or flat iron rods, yetunder someconditions they may be advantageously made of steel. 1

While I have illustrated and described the best mode now-known to me forcarrying out my invention, I do not wish to be limited to the detailsabove set forth; because many modifications will suggest themselves topersons skilled in the art to which my improve- JAMES B. RYAN.
